What causes tingling lips?
Tingling lips can be the result of peripheral nerve or skin damage in the lips and surrounding tissues. Chemicals, food, and sun exposure can cause burns that lead to tingling lips, and disorders that affect the nerves, such as peripheral neuropathy, may also cause tingling lips.

Tingling lips may have several common causes including:
- Allergic reactions to food
- Chapped lips
- Chemical burn
- Cold sore (herpes simplex virus infection)
- Exposure to extreme cold or heat
- Lip injury

Tingling lips can also be caused by certain diseases and conditions including:
- Cervical spinal stenosis (a disorder of the spine in the neck area, that can cause nerve damage)
- Guillain-Barré syndrome (autoimmune nerve disorder)
- Multiple sclerosis (disease that affects the brain and spinal cord causing weakness, coordination, balance difficulties, and other problems)
- Shingles (reactivation of the varicella-zoster virus, which remains in the body in an inactive state following chickenpox)
- Systemic lupus erythematosus (disorder in which the body attacks its own healthy cells and tissues)
- Vitamin deficiency, especially vitamin B12 and folate
